DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS OF THE INVENTION

Embodiments provide improved systems and methods for gatheringinformation during a wildfire or other short term event (e.g. days toweeks to months), typically from multiple (2 or more, 10 or more or even100 or more) Real-Time unmanned Surveillance and Data Acquisition sensorarrays Units (RTSDAUs) or more simply Data Acquisition Units (DAUs)deployed at strategic locations around a fire (e.g. on ridges, invalleys or canyons, around escape routes, around structures, and thelike) or other situations (e.g. post wildfire slide or mudflow regions)that could benefit from monitoring. Such apparatus may include one ormore working heads that may include various sensors, actuators, ahousing, shields, water jackets, batteries, battery charging systems(solar, wind, thermal electric generators, or the like), one or morefixed, adjustable, or even actuatable legs for positioning and orientingthe working heads (e.g. 5-8 feet, or more, off the ground with, forexample, a nominally horizontal primary orientation), open or windowedhousings, motors or actuators for reorienting position (e.g. of cameraviewing direction). In some implementations, batteries may be locatedaway from the working heads, e.g. in shielded housings on the ground atthe base of a DAU. Gathered data is transmitted by RF, wired, or otherwireless technology to local or central command centers where the datais received directly by one or more command and control consoles, CCC(e.g. computers and display panels running specialized software). Insome cases, particularly when the monitored area is not too large, theCCC might take the form of a laptop, tablet, cell phone, or the likewhile in other cases, e.g. when a larger area to be monitored exists,the CCC functionality might be divided between multiple laptops, or thelike, and may also use supplemental displays (e.g. LED, LCD, plasmadisplays, projectors, or the like). The data display may occur via textbut in the most preferred embodiments the majority of data is displayedin a graphical or image-based format over a map (e.g. a topo map, asatellite image, a real-time visual image or IR image gathered by asatellite, drone, helicopter, or the like) of the region based on GPScoordinates of the individual DAUs. Information gathered and transmittedmay include for example wind direction, wind speed, air temperature,humidity, barometric pressure, directional IR levels around and abovethe sensor array, visual images and/or IR images, GPS coordinators,compass direction, gravity direction (e.g. this may be used to detectsystems that have fallen over), DAU status, and the like. In the mostpreferred embodiments imaging systems will provide vision capability inmultiple directions (e.g. forward-backward, side-to-side, in 60-degreeintervals circumferentially around the array and possibly above thearray or at various angles (e.g. to provide visual or IR imaging ofember movement), and/or or they may be directable in a programmed orcommanded manner. IR imaging sensors may measure relevant IR informationassociated with a fire using filtered wavelength bands that arenon-existent in ground level solar radiation so that solar radiationdoesn't blind or otherwise interfere with the detection of flying embersor relevant fire related detections. In some embodiments, actuatedcamera scanning may be eliminated. In some embodiments, still or videocamera functionality may be completely eliminated in favor ofdirectional IR sensing. In some embodiments imaging system orientationmay be dictated by the wind direction. In some implementations, DAUs orat least the sensor array portions thereof (e.g. working heads), may beactuatable between a primary functioning mode and a protected mode (e.g.turtle mode), wherein the most sensitive sensor array elements or costlysensor array elements forming part of a DAU are withdrawn into aprotective shield (which may include radiation reflective shielding aswell as thermally insulative shielding and perhaps even water jacketedpockets to provide water that can boil away during high temperatureexposure events so as to maintain survivable temperature within theshielded enclosures for longer periods. The transition to protective, orturtle, mode can occur automatically based on data received from thesensor array indicating that the conditions for normal operation havebecome unfavorable or are anticipated to become unfavorable (e.g. whentemperature or IR levels become too high). Alternatively, the transitionmay occur upon command from a control center (e.g. to help protect thesystem from an upcoming water drop). In another alternative, approachingbattery depletion may dictate the transition from an operational to aprotected state. Similarly, the array may automatically come out of theprotective mode or be commanded to do so. In some embodiments, whereneed for data overrides enhanced survivability associated with enteringthe turtle mode, a DAU may be commanded to not enter turtle mode. Insome embodiments even while in protected mode, the sensor array and itscontrol systems may continue some data gathering, communication, andeven battery charging. In some implementations the sensor arrays andassociated hardware can provide radio wave repeater functionality toprovide improved overall radio communications (either for voicecommunications or data communications) during a fire. In someembodiments, the sensor arrays may not only include informationgathering and transmission capability but also data processingcapability to automatically change data transmission content whencertain events occur. For example, such a content change may occur whena fire or flying embers become visible in some direction (either as seenby a camera or by a directional IR tracker), or when wind direction,speed, temperature, humidity is changing or trending for good or bad.Alternatively, such processing of information may be limited to commandcenter computers based on raw data received. In some embodiments, theDAUs may be equipped with user interface features, displays, speakers,microphones, lights, beacons, or the like. In some embodiments radiocommunications may be line of sight based, cell tower based, satellitebased, or have a different RF basis.

Some embodiments of the invention provide for improved systems formonitoring fires and include: (1) Multiple (local or remote), unmannedinformation acquisition stations with real-time communication capability(e.g. Real-Time Data Acquisition Stations or Units, i.e. DAUs); (2) Oneor more data integration, processing, display, and possibly even controlstations (e.g. laptop computers running specialized programs possiblywith enhanced display capabilities, aka Data Integration and DisplayStations, or (DIDS); and programs, or hard coded functionality,executable by the multiple DAUs and DIDS.

In some embodiments, the DAUs may include one or more sensor, control,and communication modules (i.e. SCCMs). Some embodiments add additionalmechanical & electromechanical features to the one or morecommunications modules. In some embodiments, multiple communicationmodules may provide largely redundant functionality while in otherembodiments, different functionality might be provided by differentmodules. In some embodiments sensing functionality may be provided, atleast in part, in a distributed manner. In some embodiments, some SCCMsmay be provided with or be movable in and out of thermally shieldeddoors, walls, or housings.

In different embodiments, the DAUs may include a number of differenttypes of sensors, components, and/or functionality. For example, suchsensors, components, and functionality may include: (1) one or more GPScoordinate sensors (e.g. to provide a DAUs position information); (2)one or more compass direction sensors (e.g. to provide a DAUsorientation information or orientation information for individual DAUcomponents such as the direction a camera or IR directional sensor ispointing); (3) one or more gravity sensors (e.g. to aid in leveling aDAU or determining if it as fallen over), (4) one or more wind speedsensors; (5) one or more wind direction sensors; (6) one or moreinternal & external air temperature sensors; (7) one or more surfacetemperature sensors (e.g. to provide an indication of IR heating levelwithin a DAU); (8) one or more IR sensors, e.g. an array of IR sensorslooking horizontally and above the horizontal plane (e.g. to provide IRtracking or directional information for detecting visible fire or flyingembers) or even filtered wavelength specific IR sensors, e.g. that maybe used to separate IR readings from sources of interest from IRreadings that originate from non-interesting sources (e.g. flames are aninteresting IR source but the sun may not be); (9) one or more humiditysensors; (10) one or more barometric pressure sensors (e.g. this may beused in combination with other data to predict upcoming changes in winddirection or speed); (11) one or more elevation sensors; (12) one ormore visible image camera/video systems; (12) one or more IR imagecamera/video systems; (12) one or more microcontrollers and/or dataprocessors (e.g. in some embodiments these may include user interfacecontrols for displays, microphone, and/or speakers); (13) one or morebatteries internal to an SCCM; (14) one or more batteries external to anSCCM; (15) linear or rotary encoders (e.g. for ascertaining motor orcomponent position or as part of wind direction or wind speeddetectors); (16) force or pressure sensors (e.g. for use in determiningwind speed): (17) motors or actuators located within an SCCM or externalto an SCCM (e.g. for controlling horizontal rotational, or vertical tiltmotion of a camera or video system that is internal to an SCCM,controlling the relative movement of protective doors or shields);thermal electric coolers (e.g. to help control the environment within anSCCM or for a particular component; (18) one or more radio receivers;(19) one or more radio transmitters; (20) one or more radio signalrelays or repeaters; (21) window shielding, e.g. quartz, for protectingsensitive electronics while in operational mode and/or (22) additionalsensors or dual use of some of the above noted sensor for detectingground movement around a DAU, for example, to detect movement of theground during hillside or mudslide monitoring during rains after awildfire.

In different embodiments, the DAUs may include a number of additionalcomponents such as, for example: (1) A single pole-like leg (see FIGS.10A and 10B) with a mounting spike or positioning base with or withoutholes for locating mounting spikes or other anchoring elements (e.g.rope and sand bags); (2) A tripod-like stand or quad-leg stand forpositioning an SCCM at a desired location (see FIGS. 7A and 7B); (3) ashielded rectangular base box, a three sided pyramid base box, or foursided pyramid base box in which the SCCM may be located duringprotective mode and from which the SCCM can extend during normaloperation (see FIGS. 8A and 8B); (4) relatively short legs extendingfrom a base box for leveling the base box relative to a non-horizontalor simply non-planar positioning location (see FIGS. 9A and 9B); (5)anchors for attaching the stand to the ground or other positioningsurface (e.g. roof of a building or structure; (6) one or more batteries& protective compartments; (7) thermally shielded wiring for gettingpower from the battery to the SCCM; (8) one or more battery chargers,such as a solar panel, a wind turbine, or a thermal electric generator;(9) multimode external SCCM housing components, for example thosenecessary to convert from a protected or turtle mode to a normal oroperational mode; (10) strong, and potentially thermally insulating,durable construction materials such as steels, ceramics, rubber, quartz,aramids, and the like; (11) reflective shielding such as thin metalfoils (e.g. aluminum foil); (12) water pockets or jacketing in someshielding material to provide enhanced low temperature protection as thewater evaporates or boils away—such shielding may include plugs (e.g.wax or the like) that inhibits low temperature evaporation but whichopens to provide water evaporation or boiling away as temperature beginsto rise—such shielding may be supplied in SCCM doors, housings, in thelegs of a stand, or the like; and (13) a low volume water supply andpump for boosting water jacket performance.

FIG. 1 provides an example of what a fire behavior analyst might see ona CCC when a fire in the Santa Clarita valley area of California issurrounded by several dozen DAU devices. The burnt area may or may notbe shown depending on how the software handles fire history informationor information from other sources such as drone flyovers, data gatheringfrom visible or infrared devices carried by helicopters or other fireretardant or water dropping aircraft. When viewing, an analyst mightselect between a number of different options some of which wouldillustrate one or more of the DAUs locations and status, wind speeds anddirections, temperatures, humidity, wind speed and direction trending,temperature trending, humidity trending, DAU battery status, DAU cameraimages and/or orientations, DAU IR tracking information, or the like.Due to the wide array perspective of the figure, little about the fireand individual DAUs are shown. More could be seen, for example, byclicking on individual DAUs or drawing a rough boundary around the areato be viewed.

FIG. 2 provides an example of what a fire behavior analyst might seewhen looking at a region where DAUs are located between a fire and anumber of structures. The DAUs are being displayed in this view assimple location points. As indicated in the figure, three structuralprotection units (SPUs) have been defined (in an actual fire emergency,to the extent SPUs were available many more would be defined and locatedin proximity to the other units). Each SPU is made up of one or morefire companies (engine or engines and its or their associatedfirefighters) and may be assigned a group of structures to protect. Thered dots in the figure represent DAUs some of which are deployed awayfrom structures while other are deployed close to, or even on, thestructures. The units that are far from the structures (remote units)are intended to provide insight regarding the fire's movement to acentral command center while the close by units, or local units, areintended to provide immediate information to a specific SPU concerningfire movement and ignition around the dwellings that they are to beprotect. Due to the presence of these sensor units, firefighters in anSPU can focus more of their attention on putting out ignition sites andless on monitoring possible ignition sites around other structures intheir zones. This also may allow firefighters to stay closer together toimprove overall safety while also improving overall effectiveness.

FIG. 3 focuses attention down to only the local groups of DAUs that arebeing used directly by several SPUs to provide enhanced structuralprotection. CCCs at the command center might monitor these DAUs alongwith the remote units but most preferably each SPU has a CCC to monitorthe DAUs most relevant to it (i.e. those near its structures) andperhaps those along an escape route (if considered an issue). As withthe previous figures this figure shows the DAUs in a “display locationmode” only.

FIG. 4 depicts an even closer view of a single SPU, its structures andits DAUs along with more detailed information being provided by eachDAU. In this FIG. the CCC is displaying the DAUs data in a wind and firemode. Different symbols are used to convey different information to thefirefighters. The flames shown on the right side of the drawing may notactually be seen until this information is extracted from visual or IRcamera data. In this example, the direction of the arrows shows thedirection the wind is blowing while the size of their respective arrowheads show the local wind strength. The circle in the center of each DAUsymbol shows an IR signature overhead. If the sun is overhead, it may benecessary to have filtered IR detection so that solar blinddeterminations may be made to allow detection of other IR sources thatare overhead (e.g. flying embers). Instead of using IR trackers for thispurpose, a visible camera or IR camera with image recognition softwaremay be used. Image processing may be done at the DAUs or by the CCC. Theeight sections surrounding the central region for each DAU provide anindication as to the directions in which IR signatures are present (e.g.from flames). The DAUs having multiple arrows show erratic windconditions. In some embodiments, for example, flashing DAU images mayindicate that changes have occurred for which attention is required suchas, for example, IR signals are coming from a new direction, IR signalshave increased significantly, local air temperature has increased, aneed to enter a protected state is approaching or the DAU has alreadyentered such a state, or the like. As indicated at the top of thefigure, additional data from a given DAU can be presented in textformat. As noted previously alternative screen configurations can beshown that present different types of data for all DAUs or for someDAUs. In some alternatives different icons may be used to depictdifferent fire relevant parameters either individually orsimultaneously. In some alternative embodiments, additional non-verticaland non-horizontal IR directional sensors may be used to provideadditional pieces of information.

FIG. 5 provides a schematic illustration some elements that may beincluded in a DAU.

FIGS. 6A and 6B depict two versions of the relationship between DAUs andcommand and control consoles.

FIGS. 7A and 7B depict collapsed and expanded versions of a DAU thatuses a tripod stand and includes the ability to rotate the working headabout a vertical axis and rotate the working head to different anglesabove the horizontal plane, the device depicts a flag-like winddirection sensor and a triple cup wind speed sensor as well as domedsensor including a plurality of IR trackers. The device also includes acamera system and various other electronic modules. The legs includepads or feet that allow the insertion of spikes or other anchoringelements. Alternative devices may use different numbers of legs (e.g.four legs), different numbers of leg extension sections such as 2, 4 or5 sections.

FIGS. 8A and 8B depict open and closed versions of a DAU that includes apyramidal box-like protective housing from which the sensor array can beextended from or drawn into. The front protective shields have beenremoved so that the extendible arms, working head, battery, andcollapsible cap can be seen. The unit also includes extendable legs forleveling the device on uneven terrain. In alternative embodiments, theprotective housing may take on a rectangular-box shape, a cylindricalshape, a box with sloped sides and a vertical front and back, and thelike.

FIGS. 9A and 9B depict another alternative DAU configuration wherein thestand includes a single pole-like leg, a base and a pivotable jointbetween the two. In some variations, the base may not only include holesfor holding spikes or other anchoring elements but standoffs forproviding a more stable contact with uneven terrain. In this embodiment,the working head is topped by a shielded cap and can move up and down,out of and into a protective housing that may for example be provided bya box, cylinder, hexagonal, or other extended hollow structure.

FIGS. 10A and 10B provide another example DAU lowered into theprotective housing (FIG. 10A) and raised out of the housing (FIG. 10B).In this embodiment the pole like stand is provided with a spike and basewhich may be used to anchor the pole to the ground.

Control and command consoles (CCCs) or processing and display stations(PADS) useable with the various DAUs set forth herein may take on avariety of forms from laptop computers, workstations, tablets, and evensmart phones, or the like. Such CCCs may further include supplementalmonitors or projectors.

In use, data obtained from each DAU is periodically transmitted to theCCC, CCCs, PAD, and/or PADs so data may be displayed on a locationbasis, e.g. over a map of the region of interest, in substantially realtime. Various functionalities are possible and include for example (1)changing the display format or display content as a whole or on aDAU-by-DAU basis; (2) opening and closing visible or IR video displaysor still shot displays from individual DAUs, (3) turning selected DAUcameras to desired directions to gain additional insight about alocation, (4) communicating with DAUs as a whole or on an individualbasis, e.g. to change update rates, type of information being sent witheach update, camera type being used, camera direction, positionrecalibration, other DAU embedded functionality, and the like. In someembodiments, the CCC or PADS may directly transmit area relevantinformation to firefighters in those areas. Real time monitoring systemsas set forth herein may be used with personal electronic monitoringdevices carried by individual firefighters.

It will be apparent to those of skill in the art that numerousvariations of the embodiments of the invention are possible upon reviewof the teachings herein. Some such variations may involve completelyremoving the pole or leg portion of the DAUs in favor of other mountinghardware that may be used to attach the DAUs to some existing buildings,trees, fence posts and the like that may be located in an area ofinterest. In some embodiments, a working head may be located on acontrollable base which in turn sits on a battery or other relativelyheavy mounting structure.

In view of the teachings herein, many further embodiments, alternativemethods and systems will be apparent to those of skill in the art. Assuch, it is not intended that the invention be limited to the particularillustrative embodiments, alternatives, and uses described above butinstead that it be solely limited by the claims presented hereafter.
